ENG: Based on the methods of comparative typology, expert assessment, and system analysis for the route running through the industrial districts in Kryvyi Rih, using the methods for analyzing the sources and consequences of a key event, the combined Ishikawa diagram of the key event tree, risk maps of a key event, the analysis of hidden and direct priorities, the risk indicator of the complex effect of negative factors in emergencies during the transportation of dangerous goods (DG) was determined. The authors identified the most likely sources of the emergency: 1) A rocket attack that damaged the track resulting in uncontrolled cars’ derailment; 2) Exceeding the speed of a train with tanks; 3) Icy conditions, which led to an increase in the braking distance and an accident; 4) Oversight of traffic obstacles before moving tanks, which in turn can lead to a stoppage of the technological process, cargo spillage and financial losses. A probabilistic risk assessment was carried out based on an expert assessment of the operator’s risk and measures to reduce the occurrence of emergencies were proposed with annual costs of thousand UAH. After that, a probabilistic risk assessment map and a probabilistic assessment map of risk management effects were created, which make it possible to effectively manage and control the probable sources of an emergency and choose financial investments for measures to reduce the occurrence of emergencies. After that, it was proposed to use the combined car model 17-975(01) with all the necessary equipment as a means for quick localizing and eliminating the consequences of spills of hazardous substances during their transportation by rail in the event of an accident. The economic feasibility of using the proposed technique was also substantiated. The scientific novelty lies in the creation of models for analyzing the risk assessment of an emergency, as well as identification of possible sources and factors in the occurrence of emergencies during the transportation of dangerous goods by rail, and also the development of recommendations for their reduction. The practical significance is the implementation of the developed recommendations, based on the created model to form a special car for operational needs, with the selection of the necessary equipment for the rapid implementation of the 1st stage in localization and liquidation measures.
